Description of the invention [Technical field to which the invention belongs] The present invention relates to display devices for the military. What should be noticed is that they are used by infantry and are designed to improve their ability to advance and shoot at day and night missions. [Previous Technology] Modern infantry must be able to complete a variety of tasks, and these different tasks require a variety of display systems. In the meantime, when aiming his weapon, he may become a possible target. To overcome this drawback, for example, a video camera, which can be a CCD (Charge Coupled Device) camera, is mounted on the barrel of the weapon, and this camera is connected to the first monocular display device placed before one of his eyes This device allows soldiers to aim at a target from a compensated distance, and thus fire while still being protected. At night, to help him advance, the infantry must have a night vision system called a light intensifier system. These can be monocular systems, in other words, placed before one of the eyes and the second eye remains free, or It is a binocular system, in other words, placed before both eyes. During missions involving a large number of movement sequences, the use of a monocular device allows soldiers to maintain a wide field of vision without the need for a binocular device. Therefore, he can move forward more easily by keeping the landforms, obstacles on the ground, and the branches located in the surrounding environment, in other words, typically within a square circle of less than 5 meters. Maintaining a wide field of view also allows -5-200526918 (2) Soldiers can alert to possible attacks from all around, and display devices with light intensifiers are designed to supply enhanced images with brightness much higher than ambient light. Therefore, when a soldier raises his monocular display device, it takes a certain time before the eyes watching the enhanced image adapt to low-level light, and the eyes that have been adapted to the freedom of darkness allow the soldier to reduce his time to adapt to darkness . On the other hand, night vision binocular devices are more suitable for tasks that include a large number of observation sequences. Binocular vision allows for greater visual comfort in observations in remote environments, typically on the order of 100 meters. Therefore, to best ensure the success of various infantry missions, several display devices are required. At present, the most commonly used display systems are image-enhanced binocular devices or head-mounted displays, but none of these different systems can be used to perform all day and night tasks as they are defined above, and In addition, these systems are usually expensive and large systems. [Summary of the Invention] The object of the present invention is a monocular system, which basically includes a first monocular device that is specifically dedicated to daytime tasks, and a system that is specifically dedicated to nighttime applications. The second monocular module, the combination of the two modules forms a binocular display device. Indeed, this modular device has great advantages provided by the following features: • It has monocular night vision that facilitates movement at night without any device at one glance; • double vision with excellent visual comfort that facilitates long-term night observation Eye-6- 200526918 (3) Night vision; • Monocular compensation for aiming at the target while still being protected; • Binocular compensation for vision that is helpful for long-term night observation while still being protected. It should be noted that this modular configuration allows soldiers to wear only the modules that contribute to the current mission to their helmets, which saves them from carrying extra weight when they only need a single monocular display device. On the helmet. More precisely, the object of the present invention is a first monocular display device, which includes a mechanical body, an image source, a relay optical device, and an eyepiece. The image from the image source is captured by the relay optical device and the eyepiece. Collimating towards the observer's eyes, the relay optical device includes a half-reflective plane 稜鏡, the display device includes a telescopic protective shield disposed before the semi-reflective plane 稜鏡, and the mechanical body includes A mechanical coupling mechanism for joining the second display device to the monocular display device. Another object of the present invention is a monocular display device, which includes a mechanical body, an image source, a relay optical device, and an eyepiece. The image from the image source is collimated and observed through the relay optical device and the eyepiece. The eyes of the person are characterized in that the display device includes a telescopic flat mirror arranged in the relay optical device, and the mechanical body includes a mechanical coupling mechanism designed to engage the second display device on the monocular display device. Finally, another object of the present invention is a modular binocular display device including a first monocular display device placed in front of one eye of an observer and a placed in front of the other eye of the observer. The second monocular display 200526918 (4) device. The first device includes a first mechanical body, a first image source, a first relay optical device, and a first eyepiece. The second device includes a second mechanical body, a The second image source, the second relay optical device, and a second eyepiece are characterized by: • the first relay optical device includes a half reflection plane 稜鏡, • the first relay optical device and the first eyepiece The optical power of the assembly is the same as the optical power of the assembly composed of the second relay optical device and the second eyepiece. • The first display device includes a telescopic protective shield that can be placed in front of the semi-reflective frame. Device, the first mechanical body includes a first mechanical coupling mechanism, the second display device includes a telescopic flat mirror that can be disposed before the second relay optical device, and the second mechanical body It includes a second mechanical coupling mechanism, which is designed to be coupled with the first mechanical coupling mechanism, so that the first monocular display device can be rigidly linked with the second monocular display device or rigidly separated from the second monocular display device. When a display device is rigidly attached to a second display device, the protective shield is retracted before the semi-reflective frame; the flat mirror is also retracted, and the semi-reflective frame occupies the position of the flat mirror before the flat mirror is retracted. The image of the second image source is transmitted through the first and second relay optical devices and the first and second eyepieces through reflection and transmission through the semi-reflective chirp. -8- 200526918 (5) [Embodiment] The binocular assembly 1 is composed of two monocular modules 2 and 3. Therefore, each module must be able to operate in a self-regulating manner. The display modules can also be operated in a connected manner when they are united together, so as to form a single binocular display device only by using the semi-reflective 稜鏡 23 arranged in one of the two monocular devices, which The images from the first and second display devices can be mixed to make various operation modes possible. In Figures 1, 3 and 5, the following drawing conventions have been adopted: the thin lines are used to describe the mechanical bodies 27 and 37; the thick lines are used to describe the image source and the optical system; The path of the light, and also uses dashed lines to depict detachable parts. Fig. 1 shows a first monocular device 2 according to the present invention, which includes the semi-reflective ridge 23. In Figure 1, the device operates in a self-disciplined manner, which basically includes: • a first mechanical body 2 7 depicted in a graphic using thin lines; • a first image source 2 1 disposed within this mechanical body 2 7; A first optical assembly that basically includes a first relay optics 22, a first eyepiece 24, and a semi-reflective ridge 23. The image source 21 can be a small imager typically having a size of a centimeter level, which is also called a 'micro-display'. By way of example, an LCD can be illuminated by a light source composed of light emitting diodes. The matrix can be used as the micro-display, and the imager conveys, for example, images from a camera mounted on a soldier's weapon and targeting information. -9- 200526918 (6) This image is focused into an intermediate image by the first relay optical device 22 on the focal plane of the first eyepiece. The relay optical device is conventionally composed of different groups including optical lenses. Composed of optical devices. The semi-reflective 稜鏡 23 is arranged in these optical devices. This 稜鏡 is a thin flat 稜鏡 and-is used in the reflection mode. Its reflection coefficient is about 50%, which makes it also usable. In transmission mode, it does not benefit only one of the optical paths. It should be noted that in this configuration, half of the luminous power is lost due to transmission through the semi-reflective chirp. However, in order to compensate for this power loss, the imager only needs to have a high brightness, so that the final brightness seen by the soldier is sufficient, and it is not embarrassed by technical problems. From the middle image, the first eyepiece 24 forms a collimated image at the infinite distance seen by the observer. The exit pupil of the eyepiece and the pupil of the soldier's eye overlap. The depth of field of this eyepiece is large enough. Aim at the target comfortably, the eyepiece can be adapted to focus adjustment. The at least one flat corner mirror 25 enables the optical assembly to be folded back into a space of reduced thickness. The first mechanical body 27 provides several functions, i.e. support of various elements of the system and their protection against attacks from the external environment, which is particularly harsh for the infantry performing the task. The first mechanical body 27 also contains coupling mechanisms that allow the device to be connected to a second display device, which are not shown in the figure]. The display device also includes a telescopic protective shield 26. When the device 2 is used in a self-disciplined manner, the telescopic protective shield 26 is arranged in front of the semi-reflective 稜鏡 2 3. This opaque shield ensures a semi-reflective edge The mechanical protection of the mirror-10-200526918 (7), and at the same time prevent stray light from penetrating into the relay optical device, the protective shield 26 can be detached from the first mechanical body, as shown in Figure 1, or can be rigidly joined to the Ontology 2 7. In this case, at the retracted position, it fits into a housing arranged in the machine body and is designed for this purpose. The first mechanical body 27 may also include a mechanism for engaging it with a soldier's helmet, as indicated in FIG. 2, where the device is shown mounted on the helmet 4. In this case, the helmet includes a mechanical mounting bracket 5 designed to hold the monocular display device 2. These engaging mechanisms include mechanical parts that allow the device to be mounted on the right or left eye of the soldier. They may also include eyepieces. An adjustment mechanism that allows the exit pupil to be optimally positioned on the pupil of the soldier's eye. Therefore, the device allows the soldier to obtain a compensating aim, which is helpful for shooting, while leaving the other eye free, so that the soldier can ensure the maximum safety of the soldier when shooting. Fig. 3 shows a second monocular device 3 according to the invention, which comprises a telescopic mirror 33, wherein the device can be connected to a first display device 2. In FIG. 3, the second device operates in a self-disciplined manner, which basically includes: • a second mechanical body 3 7 depicted in a graphic using thin lines; • a second image source 3 disposed in the body 37 1;, a second optical assembly basically including a second relay optical device 32, a second eyepiece 34, and a telescopic lens 33. The image source 31 transmits an enhanced image of the external environment, which basically includes an upstream wide-angle objective lens 3 1 1 and a light intensifier 3 1 2. The upstream lens 3 1 1 forms an image of the external environment on the photosensitive surface of the intensifier, and The intensifier delivers its -11-200526918 (8) enhanced image to its back. When the intensifier does not have an image reverser device, the intensified image is naturally reversed relative to the original image from the photosensitive surface. The optical combination including the relay optical device 32, the corner lens 35 and the eyepiece 34 is configured so that the final collimated image has the same orientation as the image from the external environment. Therefore, the booster does not need to have an image reverser device. The upstream wide-angle objective lens 3 11 is adapted to a focusing mechanism. This enhanced image is focused into an intermediate image by the second relay optical device 32 on the focal plane of the second eyepiece 34. The relay optical device 32 is conventionally composed of different groups of optical devices including optical lenses 3 2 1 and 3 22. The flat telescopic mirror 33 is arranged in these optical devices, and the protective lens can be separated from the second mechanical body 37 or can be rigidly joined to the body. In this case, at the retracted position, it fits into a housing arranged in the machine body, and is designed for this purpose. In the latter configuration, the mirror is constantly protected from the outside, whether or not it is in the retracted position. From the middle image, the second eyepiece 34 forms a collimated image at the infinity seen by the observer. The exit pupil of the eyepiece and the pupil of the soldier's eye overlap. The depth of field of this eyepiece is large enough to aim the target comfortably. The eyepiece can be adapted for focus adjustment. The cube-corner mirror 35 allows the optical assembly to be folded back into a space of reduced thickness. The second mechanical body 37 provides several functions, that is, the support of various elements of the system and their protection against attacks from the external environment, which is particularly harsh for the infantry performing the task. The second mechanical body 37 is also provided. -12- 200526918 (9) Coupling mechanisms that enable the device to be connected to the first display device, these mechanisms are not shown in FIG. 3. The second mechanical body 37 may also include a mechanism for engaging it with a soldier's helmet, as indicated in FIG. 4, where the device is shown mounted on the helmet 4. In this case, the helmet includes a mechanical mounting bracket 5 designed to hold the monocular display device 2. These engaging mechanisms include mechanical parts that allow the device to be mounted on the right or left eye of the soldier. They may also include eyepieces. An adjustment mechanism that allows the exit pupil to be optimally positioned on the pupil of the soldier's eye. As a result, the device allows an enhanced view of the external environment to be transmitted to one eye while leaving the other eye idle. FIG. 5 shows the first and second display devices when the first and second display devices are combined to form the binocular device 1 by their connection mechanism. In this case, the protective mask 26 is retracted to the front of the semi-reflective ridge 23, and the plane mirror 33 is also retracted. In order for the binocular device 1 to operate correctly, three optical conditions must be met. The optical power of the assembly consisting of the first relay optical device 22 and the first eyepiece 24 must be the same as that of the second relay optical device 3 2 and the first. The optical power of the assembly composed of the two eyepieces 34 is the same; • The semi-reflective 稜鏡 of the first device accurately occupies the same position occupied before the mirror of the second device is retracted; • The distance separating the two eyepieces must also be approximately It is equal to the interpupillary distance, which is approximately 65 mm. The images from the first and second image sources are transmitted through the first and second relay optics and the first and second eyepieces by reflecting and transmitting through -13-200526918 (10) semi-reflective chirps, and Two eyes facing the viewer. Therefore, in order to ensure correct binocular vision, the transmitted images must be images with the same angular size, and therefore, the optical power of the first optical assembly and the optical power of the second optical assembly must be equal. When the booster tube 3 1 2 of the second image source is switched on and turned on, this device then causes binocular night vision with excellent visual comfort that facilitates long-term night observation. The first image source can also be switched on and turned on, and the display information in the form of a simple symbol will be seen by overlapping the two eyes and the enhanced image.
